Abstract:
Salmonella enterica forms biofilms that are relatively resistant to chemical sanitizing treatments. Ionizingradiation has been used to inactivate Salmonella on a variety of foods and contact surfaces but the relativeefficacy of the process against bi

Materials & Methods:
Planktonic and biofilm-associated cells were prepared in sterile 50-ml centrifuge tubes as follows. For each individual isolate sterile TSB (5 ml) was inoculated with 200 l of a stock culture and incubated overnight at 37°C to make a fresh culture (a
